Do you understand what you've done? At runtime you've added a custom 
method called 'up' to the String object you've returned. The String 
object is now a String with an extra method. It's a cool feature of 
Ruby, but not one you would want to use widely as a beginner.

And why are you still assigning to @@result?

Perhaps it would be better if you showed some real code, what you're 
actually trying to do. This 'Mycompute' example is not particularly 
useful, because right now it's just a wrapper for a String.
